Choppy 1080p video on my MBP

[Skika]

I have a MBP 15 with the 9600 gt and an Intel ssd x-25.
Why do i experience choppy 1080p material (files that are over 8 gb)??.

Are you using Plex?

Which codec do those 1080p videos use?

Have you taken a look at Activity Monitor?

I have the same problem on my 20" iMac, but I think the choppiness is due to the 1920 x 1080 being bigger than 1680 x 1050 or 1440 x 900 in your case.

Definitely need to know what codec/bitrate/playback program you're using.

Ive played two movies and they were both mkv. files.

I have tried Plex and it is better! But does it support srt. subtitles? It didn't load them when i played the movie(i got the movie file and the subtitle file named the same)

Why cant quicktime play this without a problem

Oh, i forgot to mention i am not watching it on the mbp screen but via mini display port to a full hd TV.

VLC is tricky with MKV files. You have set a Loop off in some advanced setting inside VLC and that'll most likely fix the problem.

I'll have to look at my settings at home and let you know. Its a pretty easy fix

In Plex, I think you will have to check Automatically load subtitles and if it is named the same in the same folder it should do it. You can also manually load the subtitle file, while playing the mkv, press 'M' and load it from there.

This link should help you out. Essentially, set the loop filter for H.264 to all. Don't mean to 2x post!

Definitely try VLC with this fix. 1080 mkv plays flawlessly with this fix. Even cursor moving wont trip it up

Yey

i have changed the "output module" settings in vlc from "default" to "opengl video output"

It now works smoothly!

Tnx for all the help!

Because Quicktime pretty much sucks.
